Abstract
Stitching patterns overlap to produce a corner-locked stitch pattern. The corner-locked stitch pattern includes one or more thread interlace points, and one or more overlays of threads from overlapping patterns. A network of corner-lock stitch patterns produces a mesh, which may be embroidered into a substrate, such as a medical textile or biotextile. Corner-lock stitch patterns resist puncture-induced and tension-induced deformation of mesh pores between corner-locked stitch patterns, and may be used to modulate compliance and enhance strength properties of a substrate into which they are sewn.
Claims21
A biotextile having a reinforcing mesh sewn therein, the reinforced mesh having a grid pattern comprising a plurality of pores bounded by a plurality of corner-lock stitches, so as to resist deformation and puncture of the pores, the grid pattern comprising a first pattern of a first upper thread or yarn and a first lower thread or yarn comprising a first plurality of vertices formed from a plurality of curves, angles, or a combination of curves and angles, and a second pattern of a second upper thread or yarn and a second lower thread or yarn comprising a second plurality of vertices formed from a plurality of curves, angles, or a combination of curves and angles;
- wherein each vertex of the first plurality of vertices overlaps and interlocks with a vertex of the second plurality of vertices to form the plurality of corner-lock stitches, further wherein each corner-lock stitch comprises one or more thread interlace points and two or more thread overlays in which the second upper thread and second lower thread envelope the first upper thread and first lower thread.
A biotextile having a reinforcing mesh sewn therein, the reinforced mesh having a grid pattern comprising a plurality of pores bounded by a plurality of corner-lock stitches, so as to resist deformation and puncture of the pores, the grid pattern comprising:
- a first stitching pattern extending in a first plurality of repeating curves, angles, or a combination of curves and angles, forming a first plurality of vertices, and
- a second stitching pattern extending in a second plurality of repeating curves, angles, or a combination of curves and angles, forming a second plurality of vertices;
- wherein each vertex of the first plurality of vertices overlaps and interlocks with a vertex of the second plurality of vertices to form a corner-lock stitch of the plurality of corner-lock stitches, further wherein each corner-lock stitch comprises a polygonal ring.
